plbin: Plot a histogram from binned data
Declaration
public void bin(Double[] x, Double[] y, Bin opt)Parameters
| Type | Name | Description |
|---|---|---|
| Double[] | x | A vector containing values associated with bins. These must form a strictly increasing sequence. |
| Double[] | y | A vector containing a number which is proportional to the number of points in each bin. This is a PLFLT (instead of PLINT) vector so as to allow histograms of probabilities, etc. |
| Bin | opt | Is a combination of several flags: opt=PL_BIN_DEFAULT: The x represent the lower bin boundaries, the outer bins are expanded to fill up the entire x-axis and bins of zero height are simply drawn. opt=PL_BIN_CENTRED|...: The bin boundaries are to be midway between the x values. If the values in x are equally spaced, the values are the center values of the bins. opt=PL_BIN_NOEXPAND|...: The outer bins are drawn with equal size as the ones inside. opt=PL_BIN_NOEMPTY|...: Bins with zero height are not drawn (there is a gap for such bins). |
Remarks
Plots a histogram consisting of nbin bins. The value associated with the i'th bin is placed in x[i], and the number of points in the bin is placed in y[i]. For proper operation, the values in x[i] must form a strictly increasing sequence. By default, x[i] is the left-hand edge of the i'th bin. If opt=PL_BIN_CENTRED is used, the bin boundaries are placed midway between the values in the x vector. Also see plhist for drawing histograms from unbinned data.
